COMBINED RULING AND HEAD-PR-INTING MACHINE.

" f Applicatign filed March 14, 1823. Serial No. 625,130.

To all whom it may concern u Be it known that I, Max MiiLLER, a citizenof the German Republic, and a resident of Leipzig, Germany, haveinvented a new. and useful Improved Combined Ruling and Head-PrintingMachine (for which I have filed an application in Germany on September23, 1921), of which the following is a specification. i.

It is already known to'combine ruling machines with a printing. devicewhich prints a head or any other notice upon the ruled sheet. Theseknown machines work, however, very unquietly and unreliably. Besides,the ruling device .proper and the printing device proper are ratherdistantone from the other, so that the sheets get easily displaced ontheir way from the for mertothelatten,v I v These drawbacks are obviatedin the impresent invention. The ruling machine and an impression machinewith a printing cylinder are arranged in direct succession in a frame insuch a manner that. both can be appropriatelywatched and operated, andthe ruling, as well as the printing proceed in an unobjectionable way. iw

My invention is illustrated, by way of example, in the accompanyingdrawings, in which F gure 1 1s a side-view of themachine, Figure 2 a}plan, and Figure 3 a rear;

view of it;

In the'lfront part of the machine is an ranged the ruling cylinder 2with its various ruling appliances 3. The'shaft of the ruling cylinderextends laterally outwards and has secured to it a cog-wheel .4 whichmeshes with a cog-wheel 5 that in its turn meshes with'a cog-wheel 6,afiixed to the shaft of the impression cylinder "7 The cog-wheels 4, 5,and 6 are of equal size so that the rul-' ing cylinder and theimpression cylinder rotate with the same speed. The cog-wheel 5 isadjustably connected with a cog-wheel 8 which meshes witha cog-wheel 9that is of the same size as and located immediately below, the wheel8.This latter wheel is also in gear with a smaller cog-wheel 10 thatmesheswith a large cog-wheel 12 arrangedj ranged the ink b02137 with theductor 38.

. of the cog-wheel 12 loosely upon the shaft 11.; the cog-wheel 12' isfirml attached tothis shaft and drives it. The wheels 9 and 12 areprovided with pivots located on the adjacent sidesof these wheels andcarrying 15, of which the sector 14 is attached to the wheel 9, and thesector 15 is attached to the wheel 12. The sectors 14 and 15 are solocated with respect to the rolls 13 that they extend from the one rollto the other. Besides the cogged sectors 14 and 15, also cogged sectors16 and 17 are provided which are located at the two sides of asectorshaped member 18 having at its ends forked lugs 19 and extendinginto thespace between the cog-wheels 9 and 12. The member 18 is securedto a shaft 20 which extends across the entire breadth of the machine andhas aflixed to it, besidesthe member 18, two oogged sectors 21 situatednear to the inner surfaces of the side-walls ofthe frame.

Between these walls are transverse girders 22 supporting a bed 23 uponwhich a table 24is displaceable in, guides. At the lower surface of thetable, at its longitudinal rims,

are racks 25 which mesh with cogged sectors v 21, and upon the table istheplateor form 26 attached to it.

The shaft carrying the impression cylinder-7 is supported in slidingbearings 27 which are vertically guided in slots provided in the frame;are supported by springs 28. Each of the sliding bearings is engaged bya rod 29, the

other end of which is connected with the crank-shaped end of a shaft 30arranged transversely in the frame of the machine. At one end of thisshaft, viz. at that side of the machine where there are not located thecog-wheels 9 and 12 and the sector-shaped member 18, is attached the oneend of a rocking crank bar 31, which is connected with the lower end ofa link 31, suspended at its upper end from a pivot 32 and pro-j videdwith a roll 33 which is constantly pressed against a ca1n-disk 35 bymeans of a'spring. The cam-disk 35 is secured to the shaft 11 whichsupports the cog-wheels 9 and 12.

Behind the impression cylinder 7 is ar- Below the ductor are arrangedthe rocking roller 39, the inking roller 40, and the applying roller41;This latter roller, or roll ers, if there isnio're than one, is," orare, so

the sliding bearings 27 arranged as to be adjustable in horizontal andvertical position so that it, or they, may be always properly adjustedwith respect to both the inking roller and the composition.

42 are the cords transporting the sheets of paper, and 43 areguide-rolls for these cords. 44 is the known gripping device by whichthe sheets are held upon the impres sion cylinder. 45 are transverserods arranged closely to the impression cylinder and preventing thesheets held at one end by the gripping device from turning over.

In Figure 1 the gearing is shown in its middle position. in thisposition the cogged sector meshes with the cogged sector 17 whereby theshaft is rotated in clock-wise direction and the table 24 is shoved;rearwards by the cogged sectors 15 and 17. Shortly before these sectorsare disengaged, the roll 13 attached to the end of the sector 15 andlocated at the inner side of the cog-wheel 12 has engaged the lower fork1.9 of the sector 18. hen the sectors 16. and 17 have ceased meshingwith each other, the

sector 18 is further turned for a certain length of way by the roll 13which is located at that time in the lower fork 19. As soon as, duringthe further rotation of the disk 12, the roll 13 of the cog-wheel 12leaves the fork 19, the advancing roll 13. of the cog wheel 9 enters thefork and draws it downwards. The cogged sectors 14 and 16 then mesh witheach other and rotate the shaft 20 contrarily to clock-wise direction.The table 21- is now moved forward upon the bed 23 by the cogged sectors21, After the sectors 14 and 16 have come into gear, the roll 13 of thecog-wheel 9 leaves the fork 1.9 of the sector 18, and shortly before theend of the meshing of the sectors 14 and 16 the second roll 13 of thecog-wheel 9 enters the upper fork 19 of the sector 18 and takes thisfork with it along for a certain length of way. VVhen-then. during thefurther rota tion of the cog-wheel 9. this roll leaves the fork 19, theadvancing roll 13 of the cog-wheel 12 enters already that fork and takesthe sector-piece 18 along with it upwards until the sectors 16 and 17mesh again with each other. This play is continually repeated.

The cogwheels, except the wheel 10, rotate all with the same number ofrevolutions, in consequence of which the impression cylinder makes onerotation when the ruling cylinder makes one rotation, and the table 24moves one time forward and one time rearward during that time. The speedof the table is then the same as that of the circumference of theimpression cylinder. During the movement of the parts mentioned, theimpression cylinder '5. which is supported upon crank-pins of the shaft30, is lifted and lowered by means of the rocking members 31 and 31whereby also the crank-shaft is rocked. The cylinder 7 is raised whenthe table 24 is rearwardly moved, and is lowered when the table is movedin forward direction. In the lowered position of the cylinder the sheetof paper attached to it touches the composition in the plate or form sothat the desired head. is printed upon it. The impression cylinder maybe exactly adjusted relatively to the table, or to the plate or formrespectively, by altering the position of the cog-wheels 5 and 8relatively to each other, so, that the printing is effected exactly atthe desired place of the sheet.

The sheets are conveyed from the ruling cylinder to the impressioncylinder b means of the cords 42 between which the sheets are held inproper position. There are two sets of cords which separate into uppercords and lower cords shortly in front of the impression cylinder. Theupper cords pass over the roll 47 upwards back to. the introductionplace of the ruling machine. The lower cords pass over rolls 48, 49, 50and 52, also back to that place. The sheets leaving the cords between,the rolls 47 and 48 are grasped by the grippers 44; and are drawn aroundthe impression cylinder. Shortly after the grippers have arrived intheir lowest position, they open and place the sheet, directly below thecord rolls 47 and 48, between other cords 42 which carry it away out ofthe machine. These other cords cooperate partly with the lower cords 42;they are conducted over the rolls 51, 50, 49, 53, 54, 55. Closing andopening the grippers is effected by means of a cam located upon thebearings of the shaft of the impression cylinder.

If the printing device is to be thrown out of gear, the disk 36 isturned by means of a handle 46, whereby its pivot 32 and the rockingmembers 31 are brought into such a position, that the impressioncylinder somewhat lifted. The roll of the upper rocking member 31remains, however, in contact with the cam disk 35 so that the members 31and 31 continue to rock. The impression cylinder continues to movevertically up and down but no. more to such a depth that the sheet ofpaper it carries touches the composition.

The speed of the table 24 is always the same, apart from theend-positions. By the rolls 13 engaging the forks 19 the speed of thetable is gradually decreased towards the ends of its path until it isZero, when it is again gradually increased to normal working speed, sothat no shocks arise on account of the change of direction. There arise,it is sure, a few slight irregularities in the gearing but they are veryeasily overcome by the inertia of the rotating masses. The catchingdevice may be easily manufactured with great exactness, which isparticularly inc true of the fork apertures '19 of the segment piece 18,that are formed as cycloides. Slight inaccuracies, perhaps, existing arehardly perceptible during the movement of the bed owing to theparticular arrangement and combination of the parts forming the catchingdevice, and this being so, the wear and tear arising in the course oftime, after long use of the machine, affect the move ment of the bedonly in a-neglectible meas ure. A great advantage of accelerating andfor diminishing the speed of the table consists in the feature thatcatching forks are firmly connected with the cogged sectors and aremoved in proper position relatively to the rolls solely by theappropriate movement of those sectors.
